What to do when Honda trx300 wont start?

The first thing I try to do on a simple motor like on the Honda Fourtrax is to break it down to either an electrical issue or a fuel issue.

If you hold the sparkplug up to the frame of the Honda and try starting it, you should see spark.

Why does my Honda FourTrax 300 have no spark?

I have been working on a 1990 fourtrax 300. I have no spark at all. I have checked all fuses, checked all of the connections, replaced the coil, checked the kill switch, replaced the CDI, and replaced the starter (not the problem but needed changed anyhow). The motor will crank but that’s it.

So far new parts include: coil,CDI,voltage regulator, battery,starter, and plug. One thing I did notice that was odd is that the motor will crank even when the kill switch is in the off position. Help!!! Got a test light? You sure you’re getting power at the ignition switch?

Where is the waterproof box on a Honda FourTrax?

If you haven’t, pull open the black “waterproof” box under the front plastics where the handlebar wires meet to the main harness. Last 2 older honda’s that showed up with no start but crank over were bad wires in that box.
